IMPROVEMENT IN RAILWAY-CAR WINDOWS.

Specification forming part of Letters Patent No. 178,302, dated June 6,1876; application filed March 27, 1876.

' ings and the letters of reference marked thereon, to be a full, clear,and exact description of the same, and which said drawings constitutepart of this specification, and represent, in-

Figure 1, face view; Fig. 2, transverse section.

Y This invention relates to an improvement in sashes forrailroad-coaches and like purposes, the object being to prevent thedisagreeable rattling which attends the usual construction, and theentrance of dust or air around the sash.

The invention consists in constructing the stile, one or both, in twoparallel divisions, combined with an elastic material between, as morefully hereinafter described.

A is one part, and B the second part,'0f one stile. The facing edge ofthese two parts is made concave in transverse section, as seen in Fig.2. Between the two parts a tube or solid cylinder, at, of elasticmaterial, is arranged, the

relative position, rods or supports d extend The sash is arranged inplace in the usual manner, the Whole width of the sash, when the springis free, being a little more than the width of frame from jamb to jamb,and so that in placing the sash the spring or elastic material must tosome extent be compressed, and when in place the spring reacts,expanding the sash, or hearing its edges hard against the respectivejambs, so as to prevent rattling or jarring by the movement of thecarriage or the entrance of dust or air around the sash, but yet so asto allow the sash to be easily raised or lowered.

While the cylindrical form of spring is preferable, this invention isnot confined to that form, it only being essential that the stile bemade in two parts, one movable to or from the other by means of anelastic material between the two.

I do not wish to be understood as broadly claiming the arrangement of aspring in the stile to bear against the jam'b, as such I am aware is notnew.

I claim The herein-described improvement in sashes for land and otherconveyances, consisting in the stile divided vertically into two parts,combined with an elastic material between the two, and with suitableguides to retain the said two parts in substantially the same relativeposition, substantially as specified;
